Answer:
15 goals out of 50 penalty kicks was scored by brock
Step-by-step explanation:
If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:
Number of goals scored = probability value * total penalty kicks taken
Number of goals scored = 
Number of goals scored = 
Define your variables:
Q: number of quarters
D: number of dimes
Next, create your equations
Q = 2D-4
25Q+10D=200
Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5
Substitute D back into the other equation to find Q.
Q=2D-4
Q=2(5)-4
Q=6
Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200
This works, so the answer is right! Bill has 6 quarters and 5 dimes.
Find how many times 10 seconds is in 2 minutes and 45 seconds (16 times) and then multiply that my 6 (96) Then find what half of 6 is to compensate for the leftover 5 seconds (Half of 10 - so therefore the remaining amount of cars will be half of 6) to get 99 cars.
Well since the value of C has been given to you, plug it into the equation.
F = 1.8(10) + 32
F = 18 +32
F = 50
The temperature in Fahrenheit would be 50 degrees.
